The update files of the upcoming Android 4.3 update for Sony’s Xperia Z and ZL smartphones have been leaked online. While it is unclear whether these update builds are final but considering the updates are expected to start rolling-out soon, we figure these should at-least be one of the final builds.
You can download the updates files from the source links and flash them using FlashTool, which can also be found on XDA.
A quick look at the screenshots of the updated Xperia Z suggests that there quite a few small-small user-interface tweaks; the under-the-hood changes are expected to be significant.
To remind you, Sony is set to start the official roll-out of Android 4.3 update for Xperia Z, Xperia ZL, Xperia ZR, Xperia Tablet Z, Xperia SP, Xperia Z Ultra and Xperia Z1 devices this month.
